Optical disc jitter generator and its calibration system

Abstract Jitter is one of the most important parameters for optical disc evaluation. This paper presents a design of a simulated optical disc jitter generator based on a sinusoidal frequency-modulated (FM) signal. An innovative method is proposed to calibrate the jitter generator based on the Bessel-zero method. Finally, measurement uncertainty of the calibration system is described. The results of theoretical analysis and experiments indicate that the expanded uncertainty of measurement is 0.13% in CD mode, and 0.18% in DVD mode, k = 2.
